How many three-digits can you make with the numbers 1,2,3, 4 and 5 if you can use the numbers once
Elena-2011 [213]

The total number of possible combinations to make a three digit number is 60

<u>Explanation:</u>

Given:

Five numbers are there = 1, 2, 3, 4, 5

We have to form three digit number

The number should not be repeated

Consider 3 dashes for 3 digits : ___   ___  ___

The first dash can be occupied by any 5 digits.

The second dash can be occupied by 4 digits

The third dash can be occupied by 3 digits

Thus, number of possible combinations to make a three digit number is

= 5 X 4 X 3

= 60

Therefore, total number of possible combinations to make a three digit number is 60

If the volume for 3-D polyhedra A is 200 cm3 and the volume for 3-D polyhedral B is 800 cm3, how many times bigger is the volume
Ann [662]
We're literally just comparing 200 to 800 here.
800 is 4× bigger than 200, of course.
To put that in a percent...
Well, 1 = 100%. (it's a whole)
So 4 = 400%

-4(9-3)/(8-2) = -4

(8^2-2^5)/(24/6)+3^2= 17

5(16-5)-1/(4^2-7) = 6

Hope this helps! Please rate if I helped you! Any questions please just ask! Thanks!!

Civil an airport, a factory, and a shopping center are at the vertices of a right triangle formed by three highways. the airport
vekshin1

Answer:

<em>The shortest possible length for the service road is 2.88 miles.</em>

Step-by-step explanation:

According to the below diagram, A, B and C are the positions of airport, shopping center and factory respectively.

Given that,  AB= 3.6 miles, BC= 4.8 miles and AC= 6.0 miles

In right triangle ABC

tan(\angle ACB)=\frac{AB}{BC} \\ \\ tan(\angle ACB)= \frac{3.6}{4.8}=0.75\\ \\ \angle ACB= tan^-^1(0.75)=36.8698.... degree

The shortest possible length for the service road from the shopping center to the highway that connects the airport and factory is BD.

That means, \triangle BCD is also a right triangle in which \angle BDC=90\°, Hypotenuse(BC)= 4.8 miles and BD is the opposite side in respect of \angle DCB or \angle ACB.

Now in right triangle BCD

Sin(\angle ACB)=\frac{BD}{BC}\\ \\ Sin(36.8698...)=\frac{BD}{4.8}\\ \\ BD=4.8*Sin(36.8698...)=2.88

So, the shortest possible length for the service road is 2.88 miles.
